I was sad to discover that an electric clutch ala air compresser or SC14 wouldn't work with an M90 as it would slip...
I had visions of setting up big bypass piping electronically switchable and being able to turn it off and on like Mel gibson in Mad Max..(which was bogus because theres no way to bypass it when its mounted to the valley of a V8. |

Could your engine management system adjust to turning it on and off anyway? It would be good if it could, but . . .
I seem to recall toyota's MR2 having a disengageable supercharger, i think it disengaged during idling? |

| just caught up with what ya doing the belt has to be 6pk that the profile of the ribs , anything else will slip , measure what you need by putting a drill bit in the hole of the spring tensioner to lock it in postion , get the lenght in inches and order the belt from summit racing about 40 bucks here in about 3 days , done too easy, and that includes freight , i dont buy anywhere else |

Thanks Paul,
The Holden Surburban belt fits great and it is a 6pk
I achieved my goal of using off the shelf parts so they will always be readily available even in the country when out driving. |

There would be a way to do it.. like using a belt just for the supercharger and a tensioner that could be switched on or off electronically.. then the belt could just go loose on command.... not as tidy as the clutch setup though..
just means I will chew up some juice/power spinning a supercharger I'm not using at idle... |

Yowie, a slipping belt doesn't sound viable to me, although i think this is done in some manner for the drive of ride on mowers, different belt type though.
There would surely be something readily available that would do the job? Or maybe the springs etc in the a/c clutch could be uprated?
There are also centrifugal clutches, these might be fitted to postie bikes, the spring tensions are tuned to lock-up the clutch at around the right rpm.

Yes. By my thinking . . .
The blower will still be flowing air at idle, particularly if it's a positive displacement type, and this will cause extra air friction and bearing friction, while ultimately not providing a benefit.
It's not providing a benefit because due to the higher inlet air pressure the ISC simply won't be open as much, reducing the pressure and fuel to stock levels, and stock idle speed.
Or, the ISC will be closed, yet this won't be enough, and the idle speed and fuel use will be higher than stock. |

Here you go folks...
A Holden Surburban fan belt used to spin an M90 supercharger off a Mustang now bolted to a EL falcon engine and tensioned using the factory tensioner and the EA air con one with some mods.. worked out rather well actually.
There are more photos of it here:

As I said.. think it worked out rather well...

I can see why this didn't work out Frank. The Taurus sold here had a 3.0L DOHC engine not the 3.8 used in the previous model as per that link. I think the one sold here was current from late 94 to about 97. I remember seeing a pic of a '98 which was drastically restyled (kinda like BA v's AU) and a much better looking car. Probably would have sold alright here...
Good to see you've got it all sorted anyway, I haven't caught up with your project for a while. |
